Not sure of acupuncture either, my first try didn't help. But for the hands and fingers:
In the rheum. clinic tho, they had two kinds of hand help. Didn't take it seriously first, until I realised it helps the underarms too and then that my hands do need it, I just hadn't realised...
The first was movement exercises, called spiral dynamics, which I can't find in English on the net, tho.
1a. Cup one hand solidly on something the right height, as if something were under it. Then push the hand flat. Repeat about 10x left and right.
1b. Cup it and lift each finger as high as possible.
1c. Let your hand creep forward on the table.
1d. Hold your little finger forwards and press(ure) it even more forwards.
2. Close your fingers around a short stick like a (thick?) pen in one hand, clasp and support it with the other. Then "row" a lying eight with the stick. If necessary point your forefinger out and draw the lying eight, until you've got the knack. Repeat 10x left and right.
3. Use Qi Gong balls, best youtube-video I've found is "Finger fitness guru, Greg Irwin demonstrates Chinese Medici".
The second they had was a "bath" for the hands in cold (refrigerator) or hot (under 50°) grain, preferable canola, for 15-20 mins. You move your hands around in the grain, kneading it. Canola works better because it's smaller than for instance rice.
This helped a lot of the fibro-patients there. It didn't help me at all, it gave me a dizzy spell and more for several hours, whether cold or hot, altho whole body cryotherapy is the only thing that very much helps me. I tried it a third time, seeing as my body works with stints of things, I went down to 3 minutes, then an 8 minutes break, then another 2 minutes. That was OK, but it didn't help me. It soothed pains in the fingers and hand of the others there tho.
